Abstract

An improved spreader/grader system, which includes a frame having a pair of parallel sidewalls; a plurality of spreader/grader blades positioned between the sidewalls and secured within a slot along the length of each of the sidewalls, each blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests; a hydraulic cylinder attached to each end of each blade to allow each blade to be moveable along the length of the sidewall in a parallel or non-parallel relationship as desired by the operator; and a hydraulic cylinder system for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader during the spreading/grading process. The blades of the spreader/grader may alternatively be secured in fixed positions between the sidewalls of the frame with a bolt/nut combination.

Claims

1. An improved spreader/grader system, comprising:

a. a frame having a pair of parallel sidewalls;

b. at least one spreader/grader blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests, and positioned between the sidewalls, with each end of the blade capable of being secured to each of the sidewalls in multiple positions;

c. a means for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader during the spreading/grading process.

2. The system in claim 1, wherein there are provided at least two blades positioned between the sidewalls.

3. The system in claim 2, wherein the blades are secured to the frame in a fixed position through bolting or like attachment.

4. The system in claim 2, wherein the blades are positioned parallel or non-parallel to one another.

5. The system in claim 1, wherein there may be provided a plurality of blades depending on the size of the spreader/grader.

6. The system in claim 1, wherein each end of each blade may be fixed and moveable along the length of the sidewall through the use of hydraulic cylinder attached to each end of each blade.

7. An improved spreader/grader system, comprising:

a. a frame having a pair of parallel sidewalls;

b. at least two spreader/grader blades positioned between the sidewalls and secured within a slot along the length of each of the sidewalls, each blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests;

c. a hydraulic cylinder attached to each end of each blade to allow each blade to be moveable along the length of the sidewall in a parallel or parallel relationship as desired by the operator; and

d. means for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader during the spreading/grading process.

8. The system in claim 7, wherein the means for attaching the frame to the tractor comprises a hydraulic cylinder which has the ability to lift and lower the frame from and onto the surface to be graded.

9. The system in claim 7, wherein there may be provided at least three spreader/grader blades, each operable by a hydraulic cylinder mounted on the sidewalls of the frame.

10. An improved spreader/grader system, comprising:

a. a frame having a pair of parallel sidewalls;

b. a plurality spreader/grader blades positioned between the sidewalls and secured within a slot along the length of each of the sidewalls, each blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests;

c. a hydraulic cylinder attached to each end of each blade to allow each blade to be moveable along the length of the sidewall in a parallel or parallel relationship to one another as desired by the operator; and

d. a hydraulic cylinder for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader and for listing and lowering the frame from the surface during the spreading/grading process.

11. A method of fabricating and operating a spreader/grader system, comprising:

a. providing a frame having a pair of parallel sidewalls;

b. positioning a plurality of spreader/grader blades between the sidewalls, the blades secured within a slot along the length of each of the sidewalls, each blade having a lower edge for spreading or grading a surface upon which the spreader/grader rests;

c. mounting hydraulic cylinders on each sidewall, each hydraulic cylinder attached to each end of each blade; and

d. utilizing the hydraulic cylinders to move each blade along the length of the sidewall in a parallel or parallel relationship to one another as desired by the operator.

12. The method in claim 11, further comprising the step of providing a hydraulic cylinder for attaching the frame to a vehicle, such as a tractor, for pulling the spreader/grader and for listing and lowering the frame from the surface during the spreading/grading process.
